Speckle noise restraint of SAR images based on the lifting wavelet-domain HMM model
Ying Chen · Systems engineering and electronics · 2008
Speckle noise reduction of SAR images based on the lifting wavelet-domain HMM model is predominant obviously.The wavelet base selection and lifting for the filter of the radar speckle noise is discussed.On the basis of the research of the lifting scheme wavelet technique and the relativity description of the wavelet coefficients using the Markov model,a kind of the methods of speckle reduction based on the lifting wavelet and hide Markov model is presented.The SAR images obtained aeroplane is denoised,which obtain the results well for speckle reduction of SAR Images.
